BRS Bulk Deionization Resin - Color Changing

More Views

Quick Overview

DI Resin is necessary to reduce Total Dissolved Solids (TDS) to zero and is the last stage of an RO/DI unit. Resin is sold in economical bulk bags as well as single use pouches. The resin is designed to be used with one of our refillable DI cartridges. This refillable design saves a small fortune over proprietary sealed cartridges.

Color Changing Mixed Bed DI Resin

Changes Color from Blue to Brown as the media is exhausted.

1.5 Gallon - Fills 6 standard 10" refillable cartridges

1.25 lbs. - Fills 1 standard 10" refillable cartridge

Vacuum packed in foil-lined 4mm Mylar bags to preserve quality (see Full Details for more info)

BRS Bulk Deionization Resin - Color Changing

BulkReefSupply.com takes pride in the proper packing of our DI Resin. DI resin begins depleting when exposed to air. To avoid this, we package all of our DI resin in foil-lined 4mm Mylar bags AND vacuum seal it so no air is left in the package to deplete the resin while its waiting to be used. Our resin can remain packaged this way for 2 years without losing its capacity. Our bulk DI bags are perfect for reefers who process a lot of water or otherwise go through resin quickly. The bags are resealable via a featured zipper lock. Keep in mind this won't be as good as the original seal so we recommend them only for reefers who need a high volume of DI Resin. Otherwise purchase the single refill packs for optimal freshness up to two years.

To get maximum life from your DI resin please takes the following steps

Ensure optimal operation of your RO membrane. The higher your membranes rejection rate the fewer TDS your product water will contain resulting in longer lasting resin. The best way to keep the membrane rejection rate up is to monitor and change your prefilters appropriately as well as maintain at least 50psi going into the membrane.

Ensure the resin is packed in the cartridge securely. The resin should be packed very tightly. When squeezed, there should be almost no flex to the cartridge.

The initial couple minutes of water from your RO membrane will always be high, this is commonly referred to as TDS creep. Diverting the first few minutes of water down the drain can often greatly reduce DI resin consumption.

Maintain low levels of carbon dioxide in your water supply. Excess carbon dioxide will deplete DI resin quickly. If you are depleting resin quickly and have already :addressed the two options above, excess carbon dioxide is the likely culprit. You have two choices:

Collect the water coming from your RO system in a large container, add a powerhead or air stone and allow the CO2 to gas off. Then pump the water though your DI resin.

I have purchased this DI resin several times from Bulk Reef Supply and have found it to be a cost effective alternative to purchasing pre filled cartridges. It is easy to fill your own cartridge and you can pack it well. I have found that pre-filled cartridges are under packed. I have three reef tanks which require a lot of top off water and water exchanges.

I really like the idea of the simplicity of just tossing out the old media and replacing it with new. The color change aspect is also great.

di resin straight out of a brand new bag already has 40-50% brown in it.. is it already exsausted??

Bulk Reef Supply
Hi John,
No it is not. Half of the DI resin beads are always brown and half are blue. The brown always stay brown and the blue resin changes from blue to clear as it is exhausted giving the appearance that the entire cartridge has turned brown.

I noticed that your DI resin is vacuum sealed. If I purchase the larger bag that has 6 changes in it, once I open the bag, it will no longer be vacuum sealed. Will this affect the product in any way?

Bulk Reef Supply
Hi Earl,
If you use the resin quickly it wouldn't have any sort of noticeable effect if you close the seal after each use but if you are purchasing and planning it for long term storage then you would be better off purchasing the individual bags.

Ok, I'm using a color change di resin now, not BRS, but same principle. I'm kinda new to ro/di making. The bottom of my cannister has a light brown color too it now that goes up about 2 inches. TDS is still at 0. Do you change it when just a little brown going up or wait till whole cannister has turned brown? Sorry to be so naive but like I said not been doing this long. Thanks for any suggestions you may have.

Bulk Reef Supply
Hi Valerie,
You want to wait until the TDS starts to read above 0 as the TDS meter is the ultimate say, but generally speaking that is going to correspond with the DI resin turning almost entirely brown.

Recently purchased a number of small individual vacuum sealed pouches. Is it better to store them in a fridge or freezer for prolonged life, or will room temp be more sufficient?

Bulk Reef Supply
Hi Travis,
The main enemy of DI resin is exposure to co2, which is why we use the Mylar foil lined bags and then vacuum seal them. Just store the bags in a room temperature place and you will be just fine :)
